CONTROL DEVICE FUR INTERNAL-COMBUSTZQL ENGINES.

according to the varyi the motor.

degree of adjustment Even when performed with a certain degree of skill,such adjustment must of course always be relatively inaccurate. Thearrangement, which at any rate has necessitated constant presence andattention on the part of the motor attendant, could be applied withoutconvenience in boat motors where,

too much inas a rule,

the motor attendant always stays beside the motor, but in stationar ymotors, where this is not the case, the arrangement could not be madeuse of to any ll ow, for its ob ect to bring adjustment of the fuel mentbeing effected by greater extent.

therefore, the present invention has about an automatic valve, such adustthe motor itself, and

the arrangement provided according to the invention is essentially factthat the fuel valve to be adjusted for the distinguished by the of themotor adapted control is connected with the motor or any part therewithin such a manner that a change in the speed or load of the motor of thefuel valve, action is altered.

results in the adjustment ereby the spreading In applying the invention,a centrifugal governor driven by the motor is preferably made use or,and the annexed drawing illustrates by way of diagrammaticrepresentation one embodiment of the invention provided with a governorof the said type.

Fig. 1 shows the arrangement viewed from the side, right angles to Fig.1.

and Fig. 2 is an elevation taken at According to the drawing, a commoncentrifugal governor 1 is used,

the spindle 2 of said governor being driven directly from the motor. Themounted in the spindle governor weights 3, with a sleeve 4 adapte member12,

the spindle :2, said sleeve a being preferably shaped as a double coneand having two rollers 5 bearing on the conical parts thereof, saidrollers being journalled in a sleeve 6 forming a cross ournalled pieceon a shaft 7, which is as at 8, and carries a worm 9 cooperating with aworm wheel 10 on the spindle 11 of the fuel valve.

ll is rotatable i The spindle n known manner for the purpose ofeffecting the control in question.

When the governor weights are deflected so as to displace the sleeve l,the latter with its one conical part actuates the one roller 5 so thatit will be moved from the spindle 2,

while at the same time the other roller following its corresponding coneis approached to the spindle. This will result in turning of the sleeve6 and the shaft 7 which latter transmits the tu spindle 11 of the rningmovement onto the fuel valve through themedium of the worm gear 9, 10.

The inechani al connection between the governor spindle and the spindleof the fuel valve may evidently be devised in a number of ways otherthan herein shown and described. The arrangement with the double conicalsleeve and the cross piece 6 as described and illustrated is, however,particularly advantageous,

in that it practically eliminates all dead working between the arts,while being eminently easyoperating.

The arrangement be very sensitive will therefore be found to andquiclcacting.

What I claim as new and desire to secure by Letters Patent of the UnitedStates of America is 1. In an arrangement of the character described, agovernor including a rotatable spindle,

a double conical sleeve slidably mounted upon the spindle and responsivein movement to the ported operating a rotatably supgovernor,

the

shaft, a cross piece on said shaft, and rollers upon said cross pieceadapted to bear against the conical surface of said sleeve so that whenthe sleeve is axially displaced on the governor spindle the rotatablesha ment.

ft receives a rotary move- 2. In an arrangement of the characterdescribed, a governor including a rotatable spindle, a vertica saidspindle,

spindle and oper lly slidable member within governor arms mounted on theatively connected with the member for imparting slidable movementthereto, a double conical sleeve slidably mounted on the spindle andrigidly connected with the member so as to be movable therein relativeto the spindle, a rotatably supported shaft. gearing between the shaftand the part to be operated, a cross piece on said shaft, and rollersupon said cross piece adapted to bear against the conical surface ofsaid sleeve so that when said sleeve is 10 axially displaced therotatable shaft is operated.

In testimony whereof I affix my signature.
